Product Selection and Project Engineering
During new project engineering or modification of a IS1+ Remote I/O system,
the following conditions are to be taken into account and adhered to:
Equipping and permissible dimensions
• Adhere to maximum equipping and module assignment per socket:
- For a socket with three slots:
2 CPU modules and 1 power module or 1 CPU and 2 power modules
- For a socket with four slots:
2 CPU modules and 2 power modules
• Only mount one socket for each BusRail.
• Install a maximum of 16 I/O modules per BusRail (the number of maximum I/O modules
that can be installed is also dependent on the communication protocol and functions being
used in each case. For details on this, see the corresponding IS1+ coupling descriptions).
• Adhere to the maximum system length (B BusRail extension) of 3 m.
• Plan a distance of at least 50 mm for intrinsically safe and non-intrinsically safe electrical
circuits.
Project engineering specifications depending on the ambient temperature
Adjust mounting processes based on the maximum ambient temperature,
see the "Technical data" chapter.
Updating/replacing modules
• Observe the "Upgrade to the IS1+ CPU and power module" chapter.
Redundancy options
The following redundancies can be implemented using the socket:
Simplex
Three slots socket 9496/32 with 1 x 9442/32 CPU module and
1 x 9445/32 power module
CPU redundancy
Three or four slots socket 9496/32 with 2 x 9442/32 CPU module
and 1 x 9445/32 power module
PM redundancy
Three or four slots socket 9496/32 with 1 x 9442/32 CPU module
and 2 x 9445/32 power module
System redundancy
Four slots socket 9496/32 with 2 x 9442/32 CPU module and
2 x 9445/32 power module
